Electrical and Thermal properties of semiconductor devices, Electro-thermal effects, plasma oscillations in semiconductors and semi-metals, hopping conductivity in polymeric matrix, and application of quantum Markonian master equation to describe the current noise in resonant tunneling device.

Recent interests involve quantum features of conductance in Mesoscopic Electronics that is currently a major theoretical and experimental research interest in Condensed Matter Physics. Quantum tunneling offers the possibility of very fast switching time and some day, in the not too distant future, a new "Quantum Computer" based on this quantum computing will be designed!
